Description: THERAPEUTIC DEVICE FOR A HUMAN BODY TECHNICAL FIELD The present invention relates to a traction table for treatment of among other things back problems and comprises a stand supporting a body supporting table and a foot-rest which together are revolving round a mainly horizontal axle in order to turn the body supporting table from standard position in which the foot-rest is lowered into treatment position in which the foot-rest is above the horizontal axle. The device, however, is usable for treatment positions in which the foot-rest is above or below the horizontal axle. The present invention is an improvement of a similar device known from the Swedish patent application SE-C-455 468. DESCRIPTION OF THE INVENTION The object of the present ' invention is to achieve a traction table according to the preamble which presents more advantages in relation to the device known from SE-C-455 468. The object is achieved with a traction table in which the body supporting table is supported by a frame which is pivotally connected with the stand of the table and which comprises a front stand portion and a rear stand portion. The traction table according to the invention is characterized in that at least one of the stand portions is adjustable for height whereby the front stand portion can be made shorter or longer than the rear stand portion. The traction table according to the invention is also characterized in that the locking device known from SE-C-455 468 for gradual adjustment of the body supporting table into a variety of angles of inclination combined with the stand portions which are adjustable for height can be adjusted making the body supporting table to slope in different angles of inclination in relation to the ground (floor) in addition to the angles of inclination given by the steps in the locking device. Further details and features of the traction table according to the invention are evident from the description of the drawings subsequently and from the patent claims. DESCRIPTION TO DRAWINGS The invention will be described subsequently as an example of an embodiment in connection with the accompanying drawings. Figure 1 shows a perspective view of a device according to the invention. Figure 2 shows the same perspective view of an alternative embodiment of the device according to the invention. Figure 1 shows a device according to the in- vention which comprises a stand consisting of a front stand portion 1 and a rear stand portion 2 which are tubular and connected to each other by means of a mounting plate 3 at each leg of the stand portions 1, 2. The mounting plates 3 are mounted at some distance from the free end sections of the front stand portion 1 whereas the free end sections of the rear stand portion 2 is pivotally mounted in the mounting plate 3. In the middle of the legs of the two portions 1 , 2 restriction wires or chains 4 are attached which connect the stand portions 1 , 2 to each other and prevent them from separating more than allowed by the restriction members. In that way, in side view the stand mainly is formed as an A. Each stand portion 1, 2 shows a connecting transverse foot section 11 which is telescoping within the stand and adjustable by means of pins or screws which are placed into apertures within each leg of the stand. Pivotally mounted onto the mounting plate 3 is a mainly rectangular frame 5 which on one short side shows a bracket 6 for a bar 7 supporting a foot-rest 8. On this foot-rest 8 a fixed rear foot support 9 as well as a front adjustable fixing member 10 are arranged by means of which members the feet of a person to be treated can be fastened to the foot plate 8. The bar 7 supporting the foot-rest 8 should be provided with a number of adjustment-apertures by means of which the bar can be adjusted into different positions in relation to the bracket 6 by means of a pin which can be passed through the apertures in the bar so that the foot-rest 8 can be adjusted into different positions for adjustment to the body length of the person to be treated. The frame 5 is pivoted at the mounting plates 3 and supports in turn a body supporting table 13 which supports the main part of the body of the person under treatment. In order to limit the revolving of the frame 5 as well as the body supporting table 13 around each point of suspension in the mounting plates 3 a locking device is arranged comprising a semicircular toothed locking rim 14 which is mounted to frame 5 at the mounting plate 3- The locking device comprises also a locking pin 12 which can work into notches in the locking rim 14 by moving in radial direction in relation to the locking rim 14. The notches are preferably arranged in steps of 15 . The locking pin 12 is stiffly connected with a control 15 by means of which the locking pin 12 can be displaced in radial direction out of the notches in the locking rim 14. The locking pin 12 is spring-loaded normally to be compressed into a notch in the locking rim 14. When using the device the stand portions 1 , 2 are lowered to the position shown in figure 1 and with the body supporting table 13 being mainly in vertical position and the foot-rest 8 being at the ground (floor). The person who is going to use the device loosens the foot fixing member 10 and climbs up on to the foot-rest 8 and then fastens the foot fixing member 10 so that the ankles are locked between the foot fixing member 10 and the foot support 9. Previously the foot-rest 8 has to be adjusted by means of the bar 7 to a level where the person when standing on the foot-rest with the upper part of his body reaches high enough on the body supporting table 13 so that the body supporting table when the person is reclinig will revolve round the mainly horizontal axle round which the body supporting table 13 by means of the frame 5 is pivotally mounted in the mounting plates 3 of the stand. When the person is reclining against the body supporting table and loosens the locking device by pressing the control 15 the body supporting table with the frame revolves into about the position shown in figure 1 in which position the locking pin 12 works into the first notch in the locking rim 14. The body supporting table according to the in¬ vention is covered with a plastic cloth or PTFE-plastic, as it is called, which is for sale under the trademark Teflon and which shows a very low friction towards the body of the person under treatment. The body of the person is drawn downwards and stretched by that, which results in the intended traction. By another pressing of the control 15 the locking pin 12 is moved from the first notch in the locking rim 14 and the body supporting table 13 with the frame 5 is revolved further until the locking pin works into the next notch in the locking rim. In this way the inclination of the body supporting table can be adjusted step by step into different positions until the person is lying mainly vertically with the head downwards while the traction is increasing successively. Figure 2 shows an alternative embodiment of the device according to the invention in which the frame 5 is provided with a stand 16 protruding in longitudinal direction of the frame 5 at the head end of the body supporting table 13 and which comprises two handles 17 for arm stretching and which protrudes at right angles from the plane through the upperside of the body supporting table 13 and an additional stand 18 which extends perpendicular downwards from the under side of the body supporting table 13- The handles 17 can be adjusted into different distances in between and into different distances between the handles and the body supporting table 13- The stand 18 is mounted not until the body supporting table 13 is in a mainly horizontal position and is adjustable vertically to allow a firm adjustment of the body supporting table 13 into different inclinations which allows different kinds of treatment such as massage, the stand 18 takes up weight beside the stand portions 1, 2. In order to hold the waist part of the person who is treated in place the stand is provided with a lumbar belt 19 which is fixed round the persons waist and which is attached to the stand by means of two chains 20 which are fixed to the stand e.g. with screws 21 which are screwed into a point of attachment 22 on separate T-shaped brackets 23 which are movable introduced at the foot-end of the frame 5. The brackets 23 with the points of attachment 22 are adjustable both in the longitudinal direction of the frame 5 and perpendicular to the plane through the body supporting table 13 in order to allow a correct adjustment of the lumbar belt 19 corresponding to the body length of the person to be treated. The lumbar belt 19 and the brackets 23 belonging to it are shown separately in figure 2. The stand 16 at the head end of the body supporting table 13 can also be used to support holders and tractive devices for the stretching of head and neck in which treatment the body supporting table 13 is mainly arranged horizontal. Those devices are known from pre¬ vious embodiments. By means of the telescoping foot sections 11 on each stand portion 1 , 2 the stand can be adjusted to vary the inclination of each stand portion 1 , 2 to the ground. It has shown favourable to let the foot section 11 of the front stand part 1 be more telescoped than the foot section 11 of the rear stand portion 2. Thus the foot- rest 8 on the bar 7 from the frame 5 can be taken very close to the ground (floor) without need for the foot rest 8 to telescope in between the legs of the front stand portion 1. By adjusting the position of e.g. the front foot section 11 the gradual adjustment of the body supporting table 13 can get different initial positions for adjustment of the locking device in relation to the ground (floor). Thus the locking device for gradual adjustment of the body supporting table into different angles of inclination combined with the vertically adjustable stand portions allows the body supporting table to be adjusted into different angles of inclination in relation to the ground (floor) in addition to the angles of inclination which are determined by the steps of the locking device. The detachable foot sections 11 also allow the stand to be disassembled and kept in a limited space. Like the device according to figure 1 the device shown in figure 2 is covered with a plastic cloth with very low friction towards the body of the person who is treated. The low friction allows that the treatment with clock pendulum motion, as it is called, can be carried out with a considerably lesser inclination of the body supporting table as is the case with earlier known devices. From an initial position the body supporting table 13 inclining 30° in relation to the horizontal plane and the foot-rest 8 being located above the turning point the body supporting table 13 can be pivoted for + or 15 , i.e. between 15° and 45° and can give considerate stretchings above all to that part of the back which is nearest to the pelvis. The resulting strain on the spine at the pelvis is considerably lower than the strain which arises when the body supporting table is inclined further more or is put in inverted position with the foot-rest 8 upwards. It also is possible to provide the frame 5 with leg support 24 of which one is shown dash dotted in figure 2 and on which the persons legs can be placed under treatment. Thus the device together with the stand 18 gets usable as a normal treatment table.
